Stack (Implementation)

Explore the step-by-step implementation of a stack in JavaScript using arrays. Understand core stack operations such as push, pop, isEmpty, getTop, and size, along with their time complexities. This lesson helps you master stack functionality essential for coding interviews and practical programming.

We'll cover the following...

Implementation

Introduction #

Most programming languages come with the Stack data structure built-in. However, we will be implementing a stack from scratch, which will allow you to truly master the ins-and-outs of the data structure.

Implementation #

Stacks can be implemented using Arrays or Linked Lists. Each implementation has its own advantages and disadvantages. Here, however, we will show an implementation of stacks using arrays.

As mentioned in the previous lesson, a typical Stack must contain the following ...
